D water expands when it freezes
Robert Boyle, the 17th century British chemist, first noticed that the volume of a given amount of gas is inversely proportional to its pressure when kept at a constant temperature. When working with ideal gases we use PV = nRT, but remember n, R, and T are all constant. Therefore we have:
PV(before) = PV(after)
P(0.5650) = (715.1)(1.204)
No it’s a decomposition reaction
Explanation:
Hint- look where the arrow is
If there is 1 product with an arrow next to it, then it is a decomposition reaction
This shows a product decomposing (breaking down) into 2 elements, which is a decomposition reaction
Answer:
25/12 or about 2.083g/cm^3
Explanation:
The first step is to find the volume of the box. The formula for the volume of a rectangular prism is width*height*length, which in this case is 8*6*5=240 cubic centimeters. The formula for calculating density is mass/volume, which in this case is 500/240=25/12 or about 2.083 g/ cubic centimeter. Hope this helps!
